Explanation:
It is given that,
Initial vapor pressure, P₁ = 77.86 mm
Initial temperature, T₁ = 318.3 K
Final vapor pressure, P₂ = 161.3 mm
Initial temperature, T₂ = 340.7 K
We need to find its heat of vaporization. It can be calculated by using Clausius-Clapeyron equation.




So, the heat of vaporization of a substance is 29.31 kJ/mol. Hence, this is the required solution.
Input= ?
Output= 0.75
MA= 0.33
So I just kept on Dividing numbers until I was close to "0.33" & I cam up with the answer of .......... 0.25.
So when you divide 0.25 by 0.75 you get the MA of 0.33
The last one. Opposites attract while similar ones repulse each other so all forces are pushing them apart
Explanation:
Power = work / time
Power = force × distance / time
P = (650 kg) (10 m/s²) (20 m) / (15 s)
P = 8667 W
It only occurs when there is an electric current
